摘要
目前,对导引头的干扰,归根结底是对导引头信号处理系统的干扰。它可以是能量对抗,也可以是角度、速度或距离欺骗。雷达导引头的抗干扰设计就是使雷达导引头具备干扰识别、抗干扰对策选用和抗干扰效果判决的能力。文中通过分析导引头分系统的抗干扰能力,即空间模糊度、时频域模糊度、信道的抗饱和能力、干扰识别和抗干扰逻辑管理功能几个方面,进一步阐述了单项抗干扰技术:信干比改善因子和抗欺骗干扰概率的抗干扰效果。分析了利用导引头的技术参数和抗干扰措施的性能指标,评估导引头的综合抗干扰能力。最后简述了导引头的原理及其发展。
At present, jamming to the seeker means seeker＇s signal processing system is jammed. Jamming can be performed by energy confrontation, angle, speed and range cheating. So the radar seeker has to be designed to have the ability of jamming identifying, anti-jamming countermeasures selection and anti-jamming is a effect evaluation. Jamming and anti-jamming is a complicated dynamic decision-making process. It is never practical to develop a perfect countermeasure library for electromagnetic jamming environment. In this paper, the parameters of seeker countermeasures are analyzed, such as： the space ambiguity, timefrequency ambiguity, anti-saturation ability of channel, jamming identifying and the function of anti-jamming logic management. The terms of single item anti-jamming are introduced the improvement factor of S/N and anti-deception jamming probability. Furthermore, the technical parameters and the performance specification of anti-jamming method of seeker are analyzed. The comprehensive anti-jamming capability can then be evaluated. Finally, the operation principle of seeker is briefly described and the development trend is forecasted.
